Forms of cooperation:

  • Research and development projects
  • Pilot projects dealing with the planetary mill capabilities
  • Developing of technologies of the high-energy milling and of production of composite powders

The impact of mechanical activation can manifest itself in the following effects:

  • Improvement of powder sintering parameters
  • Increase of reactivity in the solid state
  • Increase of solubility and dissolution rate
  • Activation of ores/concentrates
  • Enhancement of catalytic activity
  • Recycling of used catalysts
  • Nano-diamonds deagglomeration

Planetary mill MP-4 (TTD).


Our technologies:

  • High-energy density planetary mills allow us to accomplish grinding in 10-30 min, whereas comminution to the same particle size takes tens of hours when using conventional equipment. For instance milling of tungsten carbide (WC) down to 120 nm average particle size takes 30 min in a planetary mill of high accelerations while 15 hours are needed to obtain the same result in an analogue equipment.
  • Treatment of materials in planetary mills permits not only to accomplish fast and efficient comminution down to nano-particles but also to attain mechanical activation effects, perform mixing and mechanical alloying of powders, obtain composites and dispersion-strengthened alloys. The enhancement of various materials properties is accomplished by determination of optimal particle size and mechanical activation effects. While sintered, nanostructured particles of micrometer and submicrometer dimensions allow us to obtain materials of high density, hardness, and strength.
  • Earlier only laboratory-scale planetary mills were commercially available. Currently planetary mills of industrial scale of periodic and continuous action are produced in Russia. These mills have high accelerations in the range of 20-28 G and productivity in the range from 3 kg/h to 5 t/h. In ball mills acceleration of 1 G is used and in commercial analogies (laboratory-scale planetary mills) acceleration of 7-8 G is used, while the modern industrial-scale planetary mills have accelerations from 20 to 28 G and the modern laboratory planetary mills have accelerations from 30 up to 110 G. The specific feature of our approach is the possibility to scale-up the processes developed on the laboratory scale up to industrial level using the equipment produced by our industrial partners.
  • To meet Customer requirements we carry out determination of the optimal process conditions. These conditions depend first of all on the material properties. For the Customer material treatment to be effective it is necessary to optimize such process parameters as treatment mode and time of milling, material of the grinding bodies, milling media, and some other conditions.


We readily collaborate in the field of the development and production of new materials including nanomaterials. Partnership in R&D programs is welcome!
